TOftZZZ whom it concern:

Be ltkllOWIl that I, J onn larscnwninnn, a

,citizenof the United stat'egandla resident :of Inglewood, initheeountyiof Los- Angeles and: State of a California, have invented a new anduseful Improvement in Drinking- Fountains,of which the following isaspecification': a

Myinve'ntion is an improvementnin drinkinggfeuntains and has -'fo1'"itsobject "to provide a fountain of: the 1 character-f: specified,

especially, adapted for: the use of poultry, wherein mechanism isprovlded for retainingiwater at a certain predetermined level within'the tank, and; for preventing: access of animals other than poultry tothe} Water.

turn the valve Thenut 12'isprovided with a an annular upwardly facing:shoulder 14: intermediate 1ts ends, and with an annular rib 'or flange15 at itslower end,-the saidi rib fitting the pipe 6. 7 Theuppe'rend' ofthe pipe 6' is provided with oppositely arranged 1,7

pairsof "longitudinal slits and the-*material between the slits is bent"radially inward to form lugs l6-dianietrically oppositeeach other forengaging above the rih'orflan g e 15 to limit the upwardinoveinentfofthenut 12 and to prevent disengagenientiof thesaid nut' from' the pipe;Theupper end ofthe nut also" passes 1 through an opening I 17 wintheangulararni 18 of a bracket 19,which is secured tothe centralwall 8of thecontainer by means of rivets 20, .or' the like. The saidlolwer endof the bracket is enlarged .annu'larlyi asi'shown at; 21, and-theopenings 22 for the rivets 20 are invertica-lialinement bracket isarchedtransverselyto fit the arch ofthe centralWa-ll 3.- a I The underface" of the angularrportionyli of the bracket fits against the shoulder14 .as shown, andthe enlargedportionf2l of the of the'nut andprevents'upwardnnovem'ent p 7 off the" said 'nut. A collar '23 is threaded on tothe needle Valve below the nut, ianda set screw '24 is threaded 1through" the collar into engagement with theineedle valve to hold thecollar: in adjusted position.

a The pipe f6 is provided with an opening 25 I at the said set screw topermit access thereto to adjust the collar. The pipe 6 isvalso' providedwith a diaphrag'ni26, just abovethe upper end-of, the centralwall '3 ofthe container, and the said-diaphragm is fixed withinthe pipe and has acentral opening: topermit'the passage of the needle valve.

Af-eoil spring 27 encircles the yalvecbeand acts normally topresstheaneedlervalve upward: The'pipe6 isprovicled with a leter'afinternally threaded nipple128, just be low the" container and one end ofa curved 'tweemthecollar23=arid the diaphragm26,

pipe 29;threadedinto the saidnipple. The

said "curved pipe '29 "extends radiallyl of: the container beneath thesaine to? the" periphery thereof and, then curves upward asshown, tonear the flange, 2 of the'container; Oneend of an elbow 80 is threadedon' to the said upper end and the other enda-ofthe elbow is engaged iby;a discharge pipe 81, having a curvedwoutlet 32 delivering {to ,thecontainer, Azcover'infthe'fo-rm ofadisk 33 of nietalyor thelifkesuitable niaterialis"arranged above f the container. 7' The diskisof less diameter than the aggregate diameter of the container, that is,the dlstance from one side edge straight across to the otherside edge,andthe said coverhasa central openlng 3st for the central wall 3 of thecontainer, and at its-periphery the disk is provided with radiallyextending lugs 35 and 36,'the said lugs r the passage of the elbow 30'above the cover.-

being spaced at angular intervals of 90 and extending across the flange2 of the'contamer and resting upon the-said flangeto support the cover.a.

'Thelugs are similar, while the lug 36 is of near about the same lengthas'the lugs but of greater. width as shown in Fig. l.

,The. said lug36 is at the pipe 29 and the said'lug is slottedas shownat 37 to permit The cover is provided with a circular opening 38 at thedischarge outlet 32 of the pipe '31, and the cover is removabletopermitaccess to the container for'purposesof cleaning or repairing. It will benoticed that the lateral nipple'20'is above the'diaphragm 8 so, that theneedle valve 10 controls the'supply to the saidpipe; The container 1 isalso removable from. the pipe 6, and it may be lifted upwardly off'thepipel'6, the bracket 7181-5-19 moving therewith. The container may be:of any suitablematerial as for in- J stance, *galvanizediron, and maybe of any desired shape, the annular form being shown asa convenientform. r The screen 7 is ofywiregauze or. the like, and the diaphragms'Sand'l26 are preferably of brass, thefdiaphragm Shaving a conical openingas shown and being thevalve seat, while the diaphragm 26' has acylindrical opening and 7 The spring 27 is-the regulating means forregulating the depth of the water in the conj-tainer. Thei'collar 23 isalso preferably of brass and by adjusting the collar on the valve, thetension of the spring 27 and as a consequence the depthof the waterinthe' regulator, .may be. regulated. It .will' be noted that: the 1entire weight of the container is, supported directly by thespring 27and as soon as the nipple of the container and connected partsand thewater within exceeds .theresistance of theispring 27, the

J justed in accordance with the depth of water needle ivalve "willmovedownward, and will engage its seat to cut ofl the supply of water tothe. container. I I V The tension of the-spring may be addesired, andanyone canmaketh'e adjustment- No particular skill is required, and

the device may be arranged to provide for a Water level adjacent to theflange 2 or for any depth thatmaybe desired. Whenever the, water attainsthis depth, the weight'rof the container, its connections and the Waterwill overcome the resistance of the spring 27 and will compress the saidspring and will close, the opening through the diaphragm 8, thusshutting off the water from the container. When a portionof the waterhas beenremoved, the container will be lifted by the spring, thuslifting the needle valve and permitting the water again to thecontainer, andi thesaid cover prevents theentrance of impuritiesinto thewater and also prevents the poultry or" other animals from fouling thewater, by getting their feet 'inth e same. The free edge of,

the cover is spaced apartfronrithe outer wall of the container asuflicient distance to permit .acce'ssto the water .in the container. Itw llbe noted froman inspectioniof .fiow. The cover 83may be'rernoved toclean Figsu2 and 5, that the opening or port 00 through the diaphragm '8is frusto 'conical or tapering, the saidjopeningiincreasin-g graduallyin diameter from the underface of the diaphragm to the upper face.At'the lower end of the said opening,tha t is atthe'under 1i.

face of the-diaphragm the reduced point of the needle valve doesnotcontact with the walls of the openings,-therebeing an annu'lar spacebetween the peripheral surface of the said reduced point and the sidewall of the opening. Whenfthefneedle valve lifts, it never moves upwardfar enough to disengage the reduced point from the opening,

so that the said opening is of the same size atall times. In other wordsthe water from 5 the supply pipe willfillthe opening or port w evenwhenthe needle 'valve is closed, as

shown in Fig. 5, and as soon as the valve is lifted the water may flowinto the pipefi.
